If you actually look at those northern cloudy countries case by case they all have solutions. You can vaguely handwave at "not everywhere has hydro resource", "some countries don't have neighbors with uncorrelated wind", "offshore windns prohibitive in deep water", "some countries have cloudy winters" and so on, but where about 98% of the world live each negative in one category is met with enough positives in the other categories that it turns out that VRE is the most cost effective strategy and the gaps can he filled with existing known solutions like W2E and turbine upgrades on hydro. Having 2% of the world needing to source 30% of their electricity from gas isn't a good reason to put the brakes on the 99% of electricity and 80% of other energy that can be decarbonized much more quickly with wind and solar than any other choice. Even if it were impossible to decarbonise fully with a VRE dominant strategy, pipelining it until it hits around 50% curtailed as the emissions it avoids while nuclear is being built will be more than funding the nuclear 20% sooner and it will remain useful for producing hydrogen/ammonia/etc. In this case the optimal strategy would be fund both immediately (which china, india, japan, and france are doing), rather than using hypothetical nuclear to attack and slow real VRE buildout.
